The var is not setting and I am getting various errors. How can I do a remote “source” of a bash script file (from master.example.com) and set a shell variable locally at slave.example.com?
I need to extract each of these example.com,username,groupname,homedir,md5password,permission,secondarygroup fields and passed to the different system utilities. How do I write a shell script to automate this task and use the bash shell to parse a text file?
I‘m writing a bash wrapper script that will pass arguments to the command. I need to find out the last argument if I call the wrapper as follows:
./wrapper -a -b –longarg=foo thisfilename.txt
./wrapper -a -b thisfilename.txt
./wrapper -a –next=true thisfilename.txt
I want thisfilename.txt stored in a shell variable called $last. How do I find the last argument passed to a shell script written in bash or ksh under Unix like operating systems?
I’d like to replace / and : with _. I’m aware of the following sed command:
> s/:/_/g’ <<<"$_now"
How do I specify two pattern within the same sed command to replace | and : with _ so that I can get output as 01_20_12_16_10_42?
